Implants for Parkinsons disease. Coloured X-ray of the head of a patient receiving implants for Parkinsons disease. This view is from the side, with the front of the head at left. The eye sockets and teeth are at lower left, with neck bones at lower centre. The cranium, housing the brain, is across centre. Surgical equipment, at upper left, is being used to position electrodes in the thalmic areas of the brain. The patients head is held in a clamp, and precision measurement (stereotaxy) is being used to correctly position the electrodes. The electrodes will be used to stimulate the brain and counter symptoms, such as tremors and shaking, that accompany the incurable brain disorder Parkinsons disease.
